Best-in-class underwriter, but 2.6x book assumes a hard market that is already cresting.

The story

W. R. Berkley is a decentralized specialty and E&S underwriter with disciplined reserving, a mid-80s to low-90s combined ratio, and a short-duration portfolio that is now earning higher reinvestment yields. Trailing ROE of about 20% reflects a hard casualty and E&S market that is maturing: property rates are softening while social-inflation reserve risk is rising. The balance sheet is conservative, but the stock at about 2.56x book already prices peak-like returns.

I raised normalized ROE slightly from 14% to 14.5%. WRB has now held returns near 20% for several years, and higher investment income lifts its through-cycle floor. It is still well below the trailing figure because specialty pricing mean-reverts and reserve charges show up late in the cycle. Book growth, beta and failure risk are unchanged: retention stays high after dividends, the terminal rate is below the 5.18% risk-free rate, and leverage is low.
